Question

The wheel brake,as the name implies, is located in the wheel.It consists of a brake durm, an expander, a pull back spring, a stationary backplate, two shoes with friction linings, and anchor pins.The stationary backplate is secured to the flange of the axle housing or to the steering knuckle.The brake drum is mounted on the wheel hub.There is a clearance between the inner surface of the drun and the shoe lining.
To apply brakes, the driver pushes the foot pedal so that the expander expands the shoes and presses them to the drum.Friction between the brake drum and the friction linings brakes the wheels and automobile stops.To release brakes, the driver release the pedal,the pull back spring retracts the shoes thus permitting free rotation of the wheels
